Service account is an account that belongs to your project instead
of to an individual end user. It is used to authenticate calls
to a Google API.

To create a service account, specify the project_id and account_id
for the account. The account_id is unique within the project, and used
to generate the service account email address and a stable
unique_id.

All other methods can identify accounts using the format
projects/{project}/serviceAccounts/{account}.
Using - as a wildcard for the project will infer the project from
the account. The account value can be the email address or the
unique_id of the service account.
